the first clematis vine I trellised a month or so ago was doing awesome and is now, in only a day in a half, looking pretty much dead. the whole thing, not just a section. I tried looking for the black spots mentioned by online sources, but I don't see any. not sure why it happened. 😭

today I just had to make sure there was already an asteroid named Potato. https://www.spacereference.org/asteroid/88705-potato-2001-sv

I could try emailing the archive help desk again about it. My last few attempts have been demotivating for me. Combine with the impending budgeting doom, I'm pretty depressed and unhopeful about it all.

The previous image was a mosaic I manually assembled with no issues. It's super nice. Contrast with this automatically assembled mosaic of the nearby Orion Trapezium cluster. This is the only high level data available for this dataset. Rather than smaller, better pieces, there's one giant unusable one. sigh :(

it's so pretty, but also so incomplete... but i hate to crop it. more orion molecular clouds from the same program as hops 383 (PI Tom Megeath) https://www.stsci.edu/jwst-program-info/program/?program=5804

Removing most of the noise with G'MIC, and working through how to best represent the data. Brighter? Darker? Bluer? Redder? 🤔

So I came up with this method, which is not something I've done before that I recall. Rather than layering light upon light, I actually used the visible portion on "multiply" mode, which is a way of darkening the layers underneath it. I thought it looked good, made those hard edges much less visibly obtrusive, and helped each dataset add meaning to the other.

And then, the reason for avoiding warm colors until now, was so I could add radio data to the image, and have it be discernable from the rest.

Looking at the press release (https://chandra.harvard.edu/photo/2025/30dor/), I see that's not at all what got published, and that's fine. Instead, the visible light portion is now presented as orange, and the edges have been feathered. Some infrared data from Spitzer also was added.

In this case I thought it was even more challenging because the visible light portion of the image, from Hubble, didn't cover the whole field, and didn't reach to the "super bubble" at the lower right. Hmm. 🤔

Some Chandra x-ray data of 30 Dor I worked on last year. What got published ended up a little different. Then again, the way I created the image was kind of different, too. Combining x-rays with visible, infrared, and other types of light into a single is always challenging.
